My upper driver's side ball joint is shot. I have most of the front end appart but I can't get the nut off the top of the ball joint. The problem is, the ball joint is spinning freely so I can't break the nut free. Does anyone have any ideas how to fix this. Here's a quick illustration of my problem. I thought about grinding the nut off, but I don't have a grinder. I also thought about drilling into it but if it is hardened steel, that probably won't work either. I tried wedging a pickle fork in there but it would still spin.
